The Key Fob Components

Inside a Mercedes A Class Key Replacement key, a number of vital components work in consistency:

• The Induction Coil: A copper winding that enables the key to draw power from the ignition switch when the battery is dead.
• The IR Transmitter: Sends the security code to the EIS.
• Microswitches: The physical buttons that click when locking or opening.
• The NEC or Motorola Chip: The microprocessor that saves the special encrypted rolling codes for the automobile.

Typical Symptoms showing a Need for Repair
